Hello,
I'm using the Process class to get all the current running processes on my
machine and looking for a particular process. If I find the process, I want
to kill it. However, I've recently started recieving and exception "Error
Access is denied" when I try to kill this process. However, I can open up
Task Manager and kill the process. I'm running my program under my user name
so I don't get why I can kill it in Task Manager but my program can't kill
the process. Below is the code I'm utilizing:
for(;;)
{
proc = Process.GetProc essesByName(CPr ocWatch.PROCNAM E);
try
{
foreach (Process pr in proc)
{
if (String.Compare (pr.ProcessName , CProcWatch.PROC NAME, true) ==
0)
pr.Kill();
}
}
catch(Exception e)
{
errlog.Log("CPr ocWatch", "Error " + e.Message + " occured at: " +
System.DateTime .Now.TimeOfDay. ToString());
}
Thread.Sleep(10 000);
proc = null;
}
Can anybody tell me why I should be getting the Access denied Exception?
Any help would be much appreciate. Thanks

You can't kill a process owned by another account unless you explicitly
enable the "SeDebugPrivile ge" privilege for the calling process (that's what
Taskman does).
Note that caller needs the "Debug programs" account policy enabled (see
local policy - user right assignment).
You can use the System.Manageme nt and WMI's Win32_Process class to terminate
a process.
Or you have to enable the SeDebugPrivileg e by calling Win32 API's
LookupPrivilege Value and AdjustTokenPriv ileges using PInvoke.

I'm working on it. Thanks for your reply and I will post again once I can
get it working or if I have another question.

Willy, thanks much. I believe I have solved this little problem using
PInvoke with AdjustTokenPriv ileges. At this point, I can adjust the token
privileges but I have to wait until that process runs again to see if that
cures the problem.
Thanks again.
